A recording of a presentation at Samvera Connect 2018 described thus, prototyping a core component of our new architecture to be horizontally scalable, designing a new architecture for our digital library with a wide ranging set of requirements and users, Stanford University Library has a robust digital library system called the Stanford Digital Repository. This repository holds a little under 500 TB of materials in preservation, and a little less than that for online access, from our cultural heritage digitization efforts and institutional repository outputs. These materials are managed across 90+ codebases serving a variety of functions from self-deposit web applications, to a nearly 10 year old parallel processing framework, to a digital repository assets publication mechanism leading into our Blacklight, Spotlight, and Geoblacklight applications - among other services and needs. At the core of this system is a Fedora 3 store. With Fedora 3 now end-of-lifed, and our system suffering from limited to no horizontal scalability options, we’re revisiting our system and architecture. We are writing it from the start with a goal to have data-forward, distributed microservices and some event-driven processing components. TACO, our new core management API, is the heart of this new architecture, and is currently being developed as a prototype. This talk will walk through the process of analysing our current system via a dataflows analysis, then planning how to create ‘seams’ in our current system to migrate towards our new system in an evolutionary fashion instead of a turn-key migration. A video recording of this session is available at the 'Related URL' below., and seeing where community technologies like Hyrax, Blacklight, and IIIF will connect

Indiana University and Northwestern University, in collaboration with nine partner institutions, recently completed the last year of a three-year IMLS-funded effort to build the Avalon Media System, an open source solution for managing and providing access to digital audio and video collections, based on Fedora and the Hydra repository software development framework. As the Avalon platform reaches maturity, several institutions are in the process of implementing Avalon both to replace current time-based media access solutions and to support new use cases. In addition, new funding from the Andrew W. Mellon Foundation will support continued work to develop new features, grow and provide support for the community of adopters, and move Avalon towards organizational and financial sustainability. This panel will bring together project leaders from Indiana and Northwestern, along with Avalon community members at the University of Virginia and Stanford University, to share experiences of implementing Avalon at their institutions, integrating Avalon with other local systems, and supporting Avalon to enable a variety of use cases in research, teaching, and learning. Panel members will also discuss future development plans and provide a preview of how the project intends to transition from a grant-supported endeavor to a community-sustained solution. and Slides for a panel presentation given at the Open Repositories conference in 2015 held in Indianapolis described thus
